Using text network analysis, this research aimed to identify significant keywords associated with each period of the revised High School Engineering curriculum from 2009-2022 and to examine their interrelationships in order to analyse the observed changes. The results of this study can be summarised as follows. Firstly, a significant increase in the number of words was observed throughout the curriculum revisions, with prominent occurrences of terms such as 'engineering', 'understanding', 'problem', 'solution', 'learning', 'evaluation' and 'diversity'. Secondly, network analysis and examination of connection centrality for each subject revealed the connection relationship that represented distinct subject characteristics. Thirdly, the study of the engineering curriculum revealed shifts in emphasised content with each revision. Based on these findings, recommendations were formulated. Firstly, given the growing importance of engineering, it is imperative to conduct systematic research on engineering education in primary and secondary school contexts. Secondly, efforts should be made to strengthen the link between Engineering and Technogy･Home-economics subjects in secondary schools. Finally, high school engineering subjects should be used not only to explore engineering careers, but also to cultivate talents with interdisciplinary expertise.

The purpose of this paper is to analyze the competitiveness between Busan New Port and Shanghai's New Yangshan Port, on an island 20 miles off the Chinese mainland coast. For this aim, the paper examines backgrounds of Yangshan Port construction and its related projects, namely, Donghai Bridge and Luchao Logistics Park including operation strategies of Yangshan New Deepwater Port. The main results of this paper are as follows: Busan New Port has competitive advantage over Yangshan Port in terms of ideal location, especially in Asia-North America route, and connection between terminal and hinterland logistics park. Because Busan New Port is operated by fully on-dock system. Nevertheless, Yangshan Port has more strength in its centrality, port tariff and port productivity, which are represented by crane productivity, quay productivity and area productivity. Therefore, Korean ports are recommended by transformation from cargo attraction-type to cargo generation-type port through early activation of port logistics center along with Free Economic Zone.

This study attempted to grasp the status and perception of Uljin Geumgangsong by grasping mass media issues and user perception using big data, and to present basic data when constructing monitoring using user perception by examining the establishment relationship of agenda setting from a time-series perspective. The results of collecting and analyzing text data that can identify mass media and visitor awareness are as follows. First, both mass media and visitor keywords were related to the importance of the value and meaning of Uljin Geumgangsong. Second, in the case of the connection network, Geumgang Pine Agriculture was centered, but in the case of difference in perception between mass media and visitors, such results were derived due to the object of interest. Third, in the case of the connection relationship structure, the connection strength was strong because there were many overlapping contents of mass media. Fourth, as a result of the centrality analysis, both mass media and visitor-aware keywords were positively recognized as spaces created and maintained through institutional support, and objective perception could be grasped by finding hidden keywords. Fifth, as a result of time series analysis, it was possible to grasp the flow through the issue keywords that appeared by period, and unlike the past, it was recognized as a place for tourism and travel. Finally, as a result of examining whether the agenda setting is consistent, there is a mass media influence, so it is thought that more diverse and more information and publicity are needed by utilizing it.

The study analyzed the frequency of simultaneous occurrence of keywords presented in a total of 805 papers published in domestic journals from 1995 to 2019 by social network analysis(SNS) method, and examined core keywords of each period(5 years), in order to understand the research trends of the rural residential environment. The main results are as follows. First, as a result of the analysis of centrality, 'Community', 'Tourism' and 'Comprehensive Rural Village Development Project' were the top 3 keywords. Second, examined by each period, the top keywords are 'Eco Friendly' in 2000~2004, 'Tourism' in 2005~2009 and 2010~2014, 'Community' in 2015~2019. Third, comparing the structural characteristics of core keywords 2nd, 3rd, and 4th period, a network centering on 'Tourism' was clearly formed in the 2nd period. 'Tourism' was divided into 'Community' and a movement to form a separate group appeared in the 3rd period. In the 4th period, 'Community' was found to form a network without direct connection with 'Tourism'. The results of this study suggest the trend change of viewpoint for the rural area in the domestic research on rural residential environment. It has been confirmed that while the research had been carried out with the viewpoint of rural area as a 'tourist attraction' or 'sightseeing spot' for the urban citizens until the mid-2010s, in the research of late 2010s the viewpoint has settled down as a 'residential space' or 'space for new economic activities' of a variety of rural residents.

This study analyzed the network of low cost carriers (LCCs) to investigate the structural characteristics of airport networks. 71 LCCs in Asian major airports from January 2010 to January 2016 were queried from the SRS Analyzer Schedule Database of IATA's Airport Intelligence Service, and analyzed international routes excluding domestic flights. We analyzed the network connection mechanism focusing on Incheon International Airport, Hong Kong, Singapore, Narita, Kansai, Pudong, Kaohsiung, Gimpo and Jeju airports as well as structural changes in the LCC network using four centrality analysis concepts. The outcomes showed that the LCC network is formed in these airports and the density of connectivity to other airports increased. In recent years, LCC has launched LCCs-Alliances and would be considered to operate a hub-and-spoke network.
